Hello,
Would someone please help me about the next basic things?
I have programed microcontrollers in the past but now I need to work with ARM processors and need some basic…
Hi,
In AMBA AHB:-
For two clock cycle SPLIT or RETRY response, hgrant must be low after 1st clock cycle of SPLIT or RETRY response.
q) For two clock cycle ERROR response, is it mandatory of hgrant must be low after 1st clock…
What would happen if HREADY will be lower not after address phase, but according to HW internal logic that wants to hold CPU for some clock cycles.
Thanks
I am a Digital Verification Design Engineer.
Currently, I am in the process of developing an UVM Test Bench for AHB 2.0.
I have following questions.
1) From AHB Master side, Can BUSY cycles be inserted in middle of INCR16 burst?
2) From AHB Master side,…
Why the address boundary for AHB burst should not cross 1KB??
And in case of burst operation, is that every beat the address increment taken care by master?
Can the AMBA AHB Slave give multiple SPLIT response again to the AHB Master that has been given SPLIT response before and after updating hsplit signal for that Master by the Slave?
Hi All,
I have a question on AMBA5 AHB feature : Stable_between_Clock property
The AMBA5 AHB Specification describes:
Signals that are described as being stable are required to remain at the same value when sampled at different rising clock edges in an…
Hi ,
In AHB specs, There is one note as below.
Note
Every slave must have a predetermined maximum number of wait states that it will insert before it backs off the bus, in order to allow the calculation of the latency of accessing the bus. It is recommended…
Hi,
I have a question on AMBA AHB, Let us assume we are firing INCR4 burst from master M1.
Let us assume EBT is happened during 2nd transfer address phase of INCR4 burst (i.e Master M1 lost its grant without driving of its data phase and…
Hello....!!!
Can anyone tell the minimum and maximum frequency or bandwidth on which AMBA AHB, APB, AXI and CHI and ACE can work successfully?
The spec simply states that a master may cancel a burst after receiving an ERROR response for one of its transfers or continue with the remaining transfers.
The spec does not go on to state what the slave is supposed to do in that case though. Should it…
Hello everyone,
I want to understand the transfer continuation process from AHB MASTER during ERROR response from AHB SLAVE.
As specified in the AMBA Specifications (Rev 2.0) IHI0011A_AMBA_SPEC.pdf section 3.9.4 page no 3-23 :
3.9.4 Error response
If a slave…
Im new to the ahb protocol can any on give me an idea about retry response, when a retry response is generated from slave side.
I heard that when HTRANS is BUSY, undefined length burst (INCR) will be terminated.
But when I read a document, I saw an example that BUSY transfer followed by SEQ transfer during an undefined length burst.
Doesn't it mean that INCR is not terminated?
